Trait EditWeight

pub trait EditWeight {
    // Required methods
    fn add_cost(&self) -> usize;
    fn rm_cost(&self) -> usize;
    fn sub_cost(&self, other: &Self) -> usize;
}

Trait for types that have custom costs for addition/removal and substitution.

Required Methods

fn add_cost(&self) -> usize

Cost of adding this item to a sequence

fn rm_cost(&self) -> usize

Cost of removing this item from a sequence

fn sub_cost(&self, other: &Self) -> usize

Cost of substituting other for this item. Note: edit distance is only well-defined when self.sub_cost(&self) == 0

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
